Brocade FastIron Ethernet Switch Layer 3 Routing Configuration Guide - Manual (Page 395)

NOTE
To disable BGP4 without losing the BGP4 configuration information, remove the local AS (for example,
by entering the no local-as command). When you remove the local AS, BGP4 retains the other
configuration information but will not become operational until you reset the local AS.
BGP4 parameters
You can modify or set the following BGP4 parameters:
• Optional - Define the router ID. (The same router ID also is used by OSPF.)
• Required - Specify the local AS number.
• Optional - Add a loopback interface for use with neighbors.
• Required - Identify BGP4 neighbors.
• Optional - Change the Keep Alive Time and Hold Time.
• Optional - Change the update timer for route changes.
• Optional - Enable fast external fallover.
• Optional - Specify a list of individual networks in the local AS to be advertised to remote autonomous
systems using BGP4.
• Optional - Change the default local preference for routes.
• Optional - Enable the default route (default-information-originate).
• Optional - Enable use of a default route to resolve a BGP4 next-hop route.
• Optional - Change the default MED (metric).
• Optional - Enable next-hop recursion.
• Optional - Change the default administrative distances for EBGP, IBGP, and locally originated routes.
• Optional - Require the first AS in an Update from an EBGP neighbor to be the neighbor AS.
• Optional - Change MED comparison parameters.
• Optional - Disable comparison of the AS-Path length.
• Optional - Enable comparison of the device ID.
• Optional - Enable auto summary to summarize routes at an IP class boundary (A, B, or C).
• Optional - Aggregate routes in the BGP4 route table into CIDR blocks.
• Optional - Configure the device as a BGP4 route reflector.
• Optional - Configure the device as a member of a BGP4 confederation.
• Optional - Change the default metric for routes that BGP4 redistributes into RIP or OSPF.
• Optional - Change the parameters for RIP, OSPF, or static routes redistributed into BGP4.
• Optional - Change the number of paths for BGP4 load sharing.
• Optional - Change other load-sharing parameters
• Optional - Define BGP4 address filters.
• Optional - Define BGP4 AS-path filters.
• Optional - Define BGP4 community filters.
• Optional - Define IP prefix lists.
• Optional - Define neighbor distribute lists.
• Optional - Define BGP4 route maps for filtering routes redistributed into RIP and OSPF.
• Optional - Define route flap dampening parameters.
